Does anyone know how to make scripts appear on the left?
You have to split the area and change the window type to the Scripts Window or Text Editor, depending whether you want to execute a script/add-on shipped with Blender or open the actual source code.


Place the cursor on the border between two windows, e.g. the 3D View and the User Preferences.
Right click and select Split Area.

Change the window type to Scripts Window for executing a script/add-on or Text Editor to load the source code of a script or write your own.





Scripts can also be executed from the text editor through Text > Run Python Script.
